Morning Job
English
Today is SPAG. We need to learn grammar rules so that we can use them in our work.
Watch the phonics link when you have finished your writing sheet.
Year 1:
Science
You will need a plastic ruler - or something similar made of plastic
a wooden ruler - or something similar like a garden cane or wooden spoon
corrugated cardboard - cut to the same size as your plastic ruler and wooden object
thinner card (cereal box strength) - cut to the same size
piece of paper (any kind)
weights - as for last week, anything which is a uniform size Lego, gravel, coins etc
We will be testing how rigid and flexible materials are.
rigid- means not at all bendy
flexible - means really bendy
Look at the pictures of bridges below, see if you can answer the question.
(The answer is - they bend a little so they don't break when the wind blows or when traffic is heavy.)
Look at the materials you have collected. Without touching them, can you predict which is the most rigid ad which is the most flexible?
We are going to experiment to see if you are correct. You can use your own idea of how to test flexibility or use this idea.
Tape down the strips onto a table edge so they lie horizontally, then use the string and tape to secure a weight on the end of the strip / solid object. You will need to measure the bendiness of each material in turn. Count how many of the weights it takes for the object to bend and write it down.
This is the recording sheet I will be using in class.
